Software settings and tools
If you are scanning bright surfaces in mouth (e.g.
golden restorations, brackets) or dental gypsum
models, click on the Scan Model symbol to dim
the scanning mode.
After scanning, you can rene the scanned model
by using the Eraser tool to remove tongue or
cheeks from the scan.
Scanning process – Upper arch
Scanning upper arch
Activate the scanner by pressing the upper
scanner button once.
Start scanning from the occlusal surface with the
tip of the scanner pointing towards the distal.
Scan the occlusal of the entire arch.
On the anteriors, rotate back and forth from the
palatal to the facial to capture data on all three
surfaces to avoid possible errors in stitching.
Scan all of the buccal.
The scan should continue from the occlusal
surface already captured and overlap with it.
Scan all of the palatal.
The scan should continue from the occlusal
surface already captured and overlap with it.
Stop the scanner by pressing the upper button of
the scanner once.
Generating and evaluating model
After scanning the upper arch, press both
buttons of the scanner at the same time to
access the menu. Press the lower button to scroll
to Generate Model and press the upper button to
select the action.
You can also click on the Generate Model button
on the screen or press M on the keyboard.
To evaluate the model for missing data, select
the gypsum model from the menu.
Next, rotate the model and analyse it for areas
which appear blue and indicate missing data:
• Dark blue areas are missing data and must
be scanned again, if the data is missing at the
area of interest.
• Light blue areas have low but enough data
density and usually do not need to be
rescanned.
If necessary, rescan (dark blue) areas with
missing data.
Place the scanner over an area already scanned,
restart the scanner by pressing the upper button
and hold it still.
When you hear the sound, the scanner is
capturing data again.
Once you are ready, move on to the opposite
arch by pressing the lower button of the scanner,
which activates Lower Prep as the layer.
If you have rescanned the model, the model is
now generated again automatically.
Scanning process – Lower arch
Scanning lower arch
Activate the scanner by pressing the upper
scanner button once. Start the scan from the
same side as with the upper arch.
Start scanning from the occlusal surface with the
tip of the scanner pointing towards the distal.
Scan the occlusal of the entire arch.
On the anteriors, rotate back and forth from the
lingual to the facial to capture data on all three
surfaces to avoid possible errors in stitching.
Scan all of the buccal.
The scan should continue from the occlusal
surface already captured and overlap with it.
Scan all of the lingual.
The scan should continue from the occlusal
surface already captured and overlap with it.
Stop the scanner by pressing the upper button of
the scanner once.
Generating and evaluating model
After scanning the lower arch, press both buttons
of the scanner at the same time to access
the menu. Press the lower button to scroll to
Generate Model and press the upper button to
select the action.
You can also click on the Generate Model button
on the screen or press M on the keyboard.

missing data.
Place the scanner over an area already scanned,
restart the scanner by pressing the upper button
and hold it still.
When you hear the sound, the scanner is
capturing data again.
Once you are ready, continue to buccal bite
to scan the teeth in occlusion. Press the lower
button of the scanner to activate Buccal Bite as
the layer.
Scanning process – Buccal bite
Scanning buccal bite
Activate the canner by pressing the upper button
of the scanner. Start the scan from the same
side as the previous scans.
Start with the buccal surface of the upper molars.
Hold the scanner still and capture the teeth until
the previously scanned upper model appears on
the screen and you hear a sound signal.
If the model does not appear, move the scanner
slowly around and towards the anteriors one
tooth at a time.
Capture the lower molars on the same side as
instructed above until the previously scanned
lower model appears and you hear a sound
signal.
If the buccal models do not align correctly, select
Delete All Data and try again.
Alternatively, or if the models did not appear
after deleting the data, stop scanning and
manually align the models with the Align Buccal
tool in Romexis software.
See KaVo ProXam iOS Instructions for use for
detailed instructions.
If the buccal scan was not enough to align the
models together, select the + sign to add a
second buccal bite scan and repeat the buccal
scanning for the other side.
Generating and evaluating model
Once all buccal bite views have been aligned,
press both buttons of the scanner at the same
time to access the menu. Press the lower button
to scroll to Generate Model and press the upper
button to select the action.
You can also click on the Generate Model button
on the screen or press M on the keyboard.
Verify the bite and, if necessary, rene the
alignment automatically using the Rene
Alignment tool.
See further instructions for using the Rene
Alignment tool in the KaVo ProXam iOS
Instructions for use.
